You'll find the audio is much better in the copy posted here: https://archive.org/details/SunsetMurderCase
It was derived from this one; but I extracted the audio, cleaned it up, and synced the audio and video back together. It's a lot easier to watch. Sorry, I couldn't do anything about the acting!

Pretty mediocre but watchable film, worth 3/5, but I give it 4/5 just because I really love the Art Deco-flavoured scene with the giant bubble/ball thing. Easily the highlight of the film. If someone ever does a "That's Entertainment"-type collection of scenes from public domain films, THAT is one of the scenes they must use!

The fan dance by today's standards was just...i dunno..nothing? But todays strippers have utterly zero class whatsoever.. i know i married one once upon a time that's how stupid i was at 22.. The fan dance however was entertainment and the women didn't try to give up close biology lessons back then and didn't have an army of women to hustle watered down drinks from every sucker who walked in the door.
I saw one real class stripper years back who had jaws dropping without being anywhere near sleazy which of course was followed with sleaze for the drunks in the crowd, but then my wife found out putting an end to my hanging out in places like that for life along with her teeth prints in my arm for a year or so.:-X
This movie just dragged and the bad guy used a fake deep voice as did the lawyer. 3 stars for the classy "stripper"..

I couldn't finish watching this one. Acting was too bad. Pacing too slow. I did enjoy Sally Rand's bubble dance; it was dreamlike. As mentioned by EsTiSi, there was what sounded to me like projector noise during her dance. The sound reoccured in later scenes.

That "strange/modern dance" was part of the Art Deco style that was popular during the 1930's. Art Deco went into art, fashion and building architecture. Figurines from the 'House of Erte' reflect that period.

This copy suffers from some major technical issues that cut into one's enjoyment of the film. During large portions of the movie, including the bubble dance mentioned below the soundtrack is overwhelmed by what sounds much like a large, lumbering truck. Also, there would seem to be a number of missing scenes... or perhaps I just assume there are because of really poor pacing and strange uses of ellipses... either way the narrative suffers. On the other hand, some of the acting is enjoyable, though one should prepare to watch a good bit of strange/modern dance and hear a song or two with no relation to the plot whatsoever.

In this her final film, Sally Rand does her bubble dance with a huge ballon, which she was famous for. This is a nice little historical gem of a by-gone era.

Although there really isn't much mystery as we know who the bad guys are from the begining, the film is none the less entertaining due to some snappy patter from the supporting players.

In the film Miss Rand does what I assume was part of her famous fan dance, but it is rather hard to tell since the camera seems to have been situated in Cleveland while Miss Rand was in Hollywood and the entire thing shot thru palm fronds.

All in all it was not a waste of time to download and put onto a disc and I enjoyed this film greatly.
